Despite the significant progresses made in all-polymer solar cells (all-PSCs) recently, relatively low short-circuit current density (Jsc) and large energy loss are still quite difficult to overcome for further development. To address these challenges, we developed a new class of narrow-bandgap polymer acceptors incorporating benzotriazole (BTz)-core fused-ring segment, named PZT series. Compared commonly used benzothiadiazole (BT)-containing PYT, less electron-deficient BTz renders derivatives with significantly red-shifted optical absorption up-shifted levels, leading simultaneously improved Jsc open-circuit voltage resultant all-PSCs. More importantly, regioregular (PZT-γ) has been achieve higher regiospecificity avoiding formation isomers during polymerization. Benefiting from more extended absorption, better backbone ordering, optimal blend morphology donor component, PZT-γ-based all-PSCs exhibit record-high power conversion efficiency 15.8% greatly enhanced 24.7 mA/cm2 0.51 eV.

Abstract All-polymer solar cells (all-PSCs) based on polymerized small molecular acceptors (PSMAs) have made significant progress recently. Here, we synthesize two A-DA’D-A molecule acceptor PSMAs of PS-Se with benzo[c][1,2,5]thiadiazole A’-core and PN-Se benzotriazole A’-core, for the studies effect structure photovoltaic performance PSMAs. The possess broad absorption showing more red-shifted than suitable electronic energy levels application as polymer in all-PSCs PBDB-T donor. Cryogenic transmission electron microscopy visualizes aggregation behavior donor PSMA their solutions. In addition, a bicontinuous-interpenetrating network PBDB-T:PN-Se blend film size 10~20 nm is clearly observed by photoinduced force microscopy. desirable morphology active layer leads its all-PSC higher power conversion efficiency 16.16%.

Great progress in organic solar cells (OSCs) has been recently achieved owing to the advent of non-fullerene acceptors (NFAs). Indeed, low-bandgap NFAs ranging from 1.3 1.6 eV with broad absorption and easily tunable energy levels can utilize more radiation maintain a small voltage loss when paired suitable donors. Efficient OSCs are dependent on good compatibility between donor acceptor materials, active layer morphology control, device engineering. In this review, we summarize some design synthesis strategies for NFAs, achieving low bandgap high power conversion efficiency. We also propose solutions toward innovative materials engineering advance development applications OSCs.

Despite the recent breakthroughs of polymer solar cells (PSCs) exhibiting a power conversion efficiency over 17%, toxic and hazardous organic solvents such as chloroform chlorobenzene are still commonly used in their fabrication, which impedes practical application PSCs. Thus, development eco-friendly processing methods suitable for industrial-scale production is now considered an imperative research focus. This Review provides roadmap design efficient photoactive materials that compatible with non-halogenated green (e.g., xylenes, toluene, tetrahydrofuran). We summarize to match non-fullerene cells. further review progress use more (i.e., water or alcohol) achieving truly sustainable PSC fabrication. For example, concept water- alcohol-dispersed nanoparticles made conjugated introduced. Also, important strategies develop water/alcohol-soluble completely eliminate conventional discussed. Finally, we provide our perspectives on challenges facing current materials, large-area coating techniques long-term stability. believe this will inform PSCs clean renewable energy sources.

Abstract The past three years have witnessed rapid growth in the field of organic solar cells (OSCs) based on non‐fullerene acceptors (NFAs), with intensive efforts being devoted to material development, device engineering, and understanding physics. power conversion efficiency single‐junction OSCs has now reached high values over 18%. boost results from a combination promising features NFA OSCs, including efficient charge generation, good transport, small voltage losses. In addition efficiency, stability, which is another critical parameter for commercialization also been investigated. This review summarizes recent advances field, highlights approaches enhancing stability discusses possible strategies further OSCs.

While great progress has been achieved in all-polymer solar cells (all-PSCs), the efficiency of all-PSCs is primarily limited by polymer acceptors that lack a high extinction coefficient, electron mobility, and good compatibility with donors. Here we designed developed acceptor PFA1 based on non-fullerene framework fluorine substituent 1,1-dicyanomethylene-3-indanone unit. In combination an electron-donating polymer, PTzBI-oF, blend film presents extended intensified absorption profile, enhanced favorable morphology. The optimized exhibit remarkably 15.11%, which is, to best our knowledge, highest performance yet reported for all-PSC. Of particular importance applicability as universal range donors achieve impressively efficiencies. These properties enable new molecular design strategy construction toward applications high-performance all-PSCs.
